851c,
I just started working with a Husqvarna chambered in 9.3x57R/360-2 1/4", And as I recall the German load was around 1.8 -2 grams of R5 powder with around a 200-grain bullet. Axel uses VV140 to replace R5 due to a very similar burn rate. I happen to use IMR (military pull down) 4895 to replace R5, for the same reason. Of course, IAW normal handloading procedures you need to reduce the charge weight and work back up, watching for signs of problems. Older rifles may have used heavier lead bullets than those used today. The rifle will tell you what it wants as you search for a load that regulates. My rifle uses close to .370" bullet but yours would likely be around .358-9", most marked 118.35 are but you should slug the barrel. If the rifle is black powder proofed, a common black powder to smokeless conversion is 45% of the black powder charge in IMR 4198. Of course, the reduction and work back up procedure applies here also. I use original length (2.125-130") 38-55 cases, but most people use 9.3x72R cases shortened to around 2.250".

To answer your actual question, the 360-2 1/4" BPE load was 50 grains BP with either 155grain, 190 grain, or 215grain bullet. The Nitro for black load was 22grains of cordite with a 190grain bullet. The Nitro Express load was 30grains Cordite and a 300grain bullet.
